Einstein once said: “If the bee disappears from the surface of the earth, man would have no more than four years to live.” In the past five years, billions of honeybees simply vanished for reasons still obscure. If the bees keep dying, there will be drastic effects for humans as well: more than one third of our food production depends on pollination by honeybees and their lives and deaths are linked to ours.

With dazzling nature photography, Academy Award®–nominated director Markus Imhoof (The Boat is Full) takes a global examination of endangered honeybees — spanning California, Switzerland, China and Australia — more ambitious than any previous work on the topic.
